Io

July 5, 2012: Scotty Degenhardt (Santa Fe, NM), a pioneer in the use of video for timing eclipses of solar system and stellar objects and a research member of the International Occultation Timing Association (IOTA), has informed the AAVSO of a research project he and colleagues are working on: modeling the Jovian dust field, moon atmospheres, and Io’s Torus through Jovian Extinction Events (JEE). He has invited AAVSO observers to participate by observing these Jovian extinction events and reporting their observations.
